Let X ~ N(2,5), Y ~ N(3,4) and Z = 3X – 2Y + 1. Suppose that X and Y are independent variables. Determine the following a) E(Z) and V(Z) b) P(0 < Z < 1.5)

F=ma is the relationship where, F is force, m is mass and a is acceleration.

Newton's second law states that  the unbalanced force applied to the object accelerates the object which is directly proportional to the force and inversely to the mass.

If we apply force to a toy car then It will accelerate.

This is how Newton's second law of motion is verified.
